tan(163)

<-- Enter angle or number for inverse functions. Enter PI for π


Calculate tan(163)°
Since our angle is greater than 90 and less than or equal to 180 degrees, it is located in Quadrant II
In the second quadrant, the values for sin are positive only.

163 is an obtuse angle since it is greater than 90°

tan(163) = -0.27

In Microsoft Excel or , you write this function as =TAN(RADIANS(163))

Since 163° is less than 90, we can express this in terms of a cofunction
tan(θ) = cot(90 - θ) = cot(90 - 163) = cot(-73)
